Thank you for the question. This question has been asked before and I am copying another Expert's answer for you here.
"A prominent plant in many lawns in late spring/early summer is white clover. White clover (Trifolium repens) is a creeping perennial. Plant stems root at the nodes where they touch the soil. The leaves are composed of 3 leaflets. Plants bloom profusely in late spring/early summer. Flower heads consist of 20 to 40 individual white to pinkish-white, fragrant flowers. White clover is common in many lawns because it is a prolific seed producer and adapts well to mowing and other lawn care practices. Its presence often is a sign of low nitrogen fertility.
White clover is a nitrogen fixer, so the idea is that you could have clover and turfgrass co-exist in a lawn and the white clover would provide some nitrogen for the turfgrass. White clover’s ability to fix nitrogen makes this weed very competitive in lawns that are not fertilized or are growing on low fertility soils.
White clover in lawns can be controlled through proper fertilization and the application of broadleaf herbicides. Products that contain 2,4-D, MCPP, and dicamba provide good control of white clover. White clover also can be controlled with herbicides containing triclopyr. Applications of the aforementioned herbicides in late spring/early summer provide some control of white clover. However, fall applications (late September to early November) are most effective.
As with the application of all herbicides, please read the manufacturer's label carefully before use".
